Kungani usebenzisa infrared

Njengoba zobuchwepheshe sasidingeka ukuhlela ukushintshanisa kwe-data usebenzisa imishini yezokuxhumana engenazo izintambo. abakhiqizi abaningi kocingo yeselula, laptops noma amaphrinta namanje ukuhlomisa imikhiqizo yabo nge-infrared zokuxhumana izindlela. Ngakho-ke yini isikhala seso lefoni (IrDA) nendlela ukuyisebenzisa? Iziphi izici okufanele kubhekwe ngendlela ukudlulisa idatha?

Okubizwa ngokuthi seso lefoni uthola igama layo ngenxa esetshenziswa wavelength. Kuyinto 860-900 NM, isb ungaphakathi uhla infrared. Ngokusebenzisa reducers, eklanyelwe adlulisa / thola idatha, sinikeza ukuxhumana okungenawaya, njengemoto computer siqu.

Kunezindlela eziningana ukuxhuma transceiver:

1. Ukuze ekhethekile IrDA-isixhumi phezu umbadlana. Izinkampani eziningi umphelelisi imikhiqizo yayo. Kulokhu, uma ukhetha idivaysi, zama unamathele nomakhi eyodwa mikhiqizo. Funda ngokucophelela imiyalelo futhi uthintane nomthengisi wakho.
2. Ezinye izinhlobo transceivers zenzelwe bahlinza akhulumele isixhumi.
3. Futhi ekugcineni, indlela yokugcina ukuxhuma port IR - USB-isixhumi. Lona elula kunazo futhi luphephile - ngokuya hardware ne-software ukuhambisana - indlela ukuxhuma. Ngokuvamile kulesi simo uhlelo uqobo esikhomba exhunywe IR Transmitter kanye iqala ukusebenza.

Kufanele kuqashelwe ukuthi le nhlobo yedatha - ngokwanele kwendle kanye kuphoqa isimo sengqondo ngokucophelela. Ngomsebenzi wokugqokwa nzile zaleli kwakwakhe njengenhlangano seso lefoni kanye transceiver kumele esihlukaniswe nazo zonke ukuphazamiseka okungenziwa. Lezi zinto ezilandelayo kumele kubhekwe:

1. elangeni.
2. Ukukhanyisa ngu amashubhu Fluorescent.
3. Ithonya amadivayisi eduze futhi kufakwe kokuba efanayo yokusebenza Isimiso: elawulwa kude, video amakhamera, amafoni ungenantambo, njll ...

Ngaphandle nemiphumela ethile engathandeki ngenhla, ukuxhumana nge-infrared engavimba ibanga. Njengoba umkhuba ubonisa, kukhona ukuhlobana esigculisayo ibanga engekho ngaphezu kuka-10 amasentimitha, futhi uma ukhipha ezingaphezu kuka 1 imitha ubalekela ngokuphelele.

Kodwa, naphezu kwazo zonke amaphutha, le ndlela kwaba zithandwa futhi ligcwaliswe kahle nge uxhumo lezintambo. Ngalo eyenziwa amadivayisi umsebenzi ezifana abanyathelisi, ama-scanner omakhalekhukhwini nokunye. D.

Ukusebenzisa amasevisi opharetha yakho yeselula, ungakwazi ukuxhuma kwi-Inthanethi, e yabo GPRS-uxhumano. Sekuyinto ezibizayo, kodwa usuthela ku ngohambo olude noma yebhizinisi. Okusho ukuthi, noma kuphi lapho udinga ukuxhumana unomphela kwi-Inthanethi ( "NL" ngokokuqala) kanye engenayo / ephumayo sezimoto ezincane (njengoba icala ngoba). I-ISP kulokhu inkampani inikeza ngamasevisi iselula.

A ehlukile kakhulu IrDA kuyinto-Bluetooth. Amadivayisi ifakwe banayo kakhulu umsindo amasosha omzimba, ezinhle yesivinini sokuxhuma. Abakwazi isebenze at ibanga ezimbalwa amashumi amamitha kusuka komunye nomunye.
